Re: [Pce] draft-dhody-pce-pcep-domain-sequence-01

Cool, thanks Dhruv. 

Can I suggest that when you submit the new version of
draft-dhody-pce-pcep-domain-sequence, you also propose some text for
draft-ietf-pce-inter-area-as-applicability, that describes the
motivation/scope/requirements for the domain sequence
representation/encoding. 

Br, Dan.

Dear Dan, Ramon and All, 

A new update of the draft is on the way which will close all open issues. I
will hope for WG adoption after that. 
Bunch of other inter-domain effort in WG (HPCE, P2MP, etc) already
references this document. As the role of
"draft-ietf-pce-inter-area-as-applicability" to cover inter-domain
applicability in a broad sense, IMHO, this work could be included/referenced
now or in later stage. 

Regards,
Dhruv

Dear Dan, all

You are right that draft-dhody should be included / referenced if/when it
becomes a wg document. I will let Dhruv comment on the issues as I was not
in Taipei, IIRC, there were some past emails on its need?.

For what is worth, I personally think that what is addressed in the draft
(i.e., the need to encode sequences, the need to constrain them and the need
to convey some order semantics) is needed. I won't be so bold to state
whether the current encoding / solution is to be retained :-), at least yet,
and we can allow some time to mature. If I may, what is your view on this?
Do you think it is addressing a non-issue?

I am afraid I don't have a clear list of them. Dhruv?

FWIW, I say yes. A personal use case is a constrain in the H-PCE computation
(IRO + order semantics). I bought Dhruv's idea that working with domains is
more flexible than working with PCE_IDs (both in hpce, and md-p2mp )

> 2. Is draft-dhody-pce-pcep-domain-sequence a suitable solution?
If it isn't we would gladly address what is needed :).

> 3. Should we adopt as a WG document?
Until now, I have not considered requesting adoption. Personally, I can wait
until it is further discussed and matures.

Thanks for your comments
R
